Firesphere House

Roderick Romero’s Firesphere House was built on three eucalyptus trees in the backyard of a Brentwood, Calif., couple. The entire house was built in Romero’s signature sustainable style using reclaimed wood, salvaged windows and vintage stained glass from Buenos Aires. The house features a large porch and viewing deck that was made from tree branches found in the yard.
